Data Sheet

V2.0, 2001-05
Sample time and conversion time of the C164CI’s A/D Converter are programmable.
Table 14 should be used to calculate the above timings.
The limit values for
fBC must not be exceeded when selecting ADCTC.
Converter Timing Example:
Assumptions:
fCPU = 25 MHz (i.e. tCPU = 40 ns), ADCTC = ‘00’, ADSTC = ‘00’.
Basic clock
fBC
=
fCPU/4 = 6.25 MHz, i.e. tBC = 160 ns.
Sample time
tS
=
tBC × 8 = 1280 ns.
Conversion time
tC
=
tS + 40 tBC + 2 tCPU = (1280 + 6400 + 80) ns = 7.8 s.
8) During the sample time the input capacitance C
AIN can be charged/discharged by the external source. The
internal resistance of the analog source must allow the capacitance to reach its final voltage level within
tS.
After the end of the sample time
tS, changes of the analog input voltage have no effect on the conversion result.
Values for the sample time
